Abstract
Paper products, such as wiping products, are disclosed that have a fabric-imprinted pattern in combination with a crepe pattern. In producing paper products according to the invention, a base web containing pulp fibers is formed. Once the base web is substantially dry, the web is creped to form a first pattern. The creped web is then placed between two moving conveyors and guided around one or more compression inducing elements. As the web is guided around the compression inducing element in between the two conveyors, shear forces and compressive forces are imparted to the web that form a fabric-imprinted pattern superimposed on the crepe pattern. In one embodiment, the fabric-imprinted pattern comprises high density troughs.
